Although most infants receive some breast milk, most are not exclusively breastfed or continue to breastfeed as long as recommended. Four out of 5 infants start out breastfeeding, but only 1 in 4 infants are still exclusively breastfed at 6 months. There are also major disparities, or differences among different groups, for breastfeeding. For example, black infants are 15% less likely to have ever been breastfed than white infants. These disparities are improving some.

Other Benefits Of Breastfeeding

Ideally, infants should be exclusively breastfed from birth until around six months old. They can continue to consume breast milk along with solid foods until they area year old or even older. This is important to the overall health of the baby and should be done whenever possible.

The benefits of breastfeeding for the child are fairly well known. Babies who are breastfed have a lower risk for asthma, obesity, type 1 diabetes, ear and respiratory infections, sudden infant death syndrome, and gastrointestinal infections like diarrhea and vomiting.

What are less well known are the benefits of breastfeeding for mothers. Not only does it lower breast cancer risk, but breastfeeding also lowers the risk of ovarian cancer. Mothers who breastfeed are less likely to develop high blood pressure and type 2 diabetes.

How Long Should You Breastfeed To Reduce Your Risk

We don’t yet have a conclusive answer to this, but research, like The Lancet study, has pointed to a trend that longer is better. Even if you supplement with formula, it appears that breastfeeding of any kind still reduces your risk. So don’t feel like it’s all-or-nothing if you’re struggling with supply issues.

Dr. Stuebe encourages the moms she sees in her practice to nurse for at least a year, or as long as both the mom and baby want toin order to receive the many benefits of breastfeeding. The AAP has the same recommendation.

Breastfeeding Helps Protect Your Child From Cancer

Breastfeeding not only reduces your chances for developing cancer, but also your childs. Evidence shows that it can help prevent your child from being overweight or obese later in life, Wohlford says. Being obese puts a person at risk for many cancers. This includes pancreatic, postmenopausal breast, endometrial, esophageal, rectal and kidney cancers.

Breastfeeding also helps strengthen your childs immune system. Your antibodies pass from your milk to your child. This helps lower your childs risks of ear infections, as well as respiratory and digestive system problems. Plus, research indicates the longer a child is breastfed, the lower his or her chances of developing allergies.

Seek a lactation consultant

Despite all the health perks, breastfeeding isnt easy. If youre considering it or having trouble, get help from a lactation consultant or a professional breastfeeding specialist. Most work in hospitals or health programs. You can ask the hospital where you plan to deliver to send a consultant to your room shortly after your baby is born. Your health care provider or childs pediatrician also can help you find one.

What Is Breast Cancer

Breast cancer is one of the most common causes of cancer deaths in women. It is a disease that develops when abnormal cells in the breast begin to multiply and form a tumor. The form of the tumor can either be benign or malignant.

Where benign tumors grow slowly and do not spread to other parts of the body, on the contrary, malignant tumors are innately dangerous as they quickly spread beyond the original tumor to distant areas of the body.

The term Breast Cancer refers to a malignant tumor that is cancerous and develops from the uncontrolled growth of breast cells.

There are mainly two types of breast cancer:

  • Invasive Ductal Carcinoma : The most common type of breast cancer, accounting for over 80% of all breast cancer diagnoses. This cancer begins growing in the duct and spreads to the surrounding breast tissues in a very short span of time.
  • Invasive Lobular Carcinoma : Another type of breast cancer that develops from lobules and spreads to the breast tissues, which are close by. It accounts for approximately 10-15% of all invasive breast cancers.
  • Apart from these two types of breast cancers, there are several other subtypes of breast cancer, such as Tubular Carcinoma, Ductal Carcinoma In Situ, and Inflammatory Breast Cancer. These cancers either incorporate characteristics of the abovementioned cancers or have unknown origins.

    Case And Control Subjects

    Information on cancer status was available for a total of 12,116 women who carried a BRCA1 or BRCA2 mutation. Case subjects were women with a diagnosis of invasive breast cancer. Control subjects were women who never had breast cancer and who were also carriers of a mutation in BRCA1 or BRCA2. Potential subjects were excluded if they were nulliparous or if information on parity was missing , if they had been diagnosed with ovarian or other cancer , if information on breastfeeding was missing , if BRCA mutation status was missing or if other pertinent information was missing . After exclusions, there was a total of 5,879 eligible women, including 2,784 women with breast cancer and 3,095 women without breast cancer .

    Breast Feeding Reduces Risk Of Breast Cancer Says Study

    How Can I Reduce My Risk of Breast Cancer?

    Breast feeding can significantly reduce the risk of breast cancer, according to a study by Cancer Research UK. The increase in the disease in developed countries is due to women having fewer children and breast feeding for shorter periods of time, the study says.

    The research is a detailed analysis of 47 published studies, with nearly 150 000 participants, from 30 countries.

    Breast cancer is the most common cancer in the United Kingdom, with more than 39 000 cases a year. Nearly a third are fatal. The research shows that the risk is reduced by 7% for each baby a woman has and that for every 12 months she breast feeds she decreases the risk by a further 4.3%.

    Currently in the United Kingdom 69% of mothers start off breast feeding, but more than half have stopped after four months. The study says that if women breast feed each child for six months longer, 1000 cases of breast cancer a year could be prevented.

    Lead researcher Professor Valerie Beral, of Cancer Research UK’s epidemiology unit in Oxford, said, “The results of this study are a major step forward in our understanding of why breast cancer incidence is so high in developed countries. It’s long been known that breast cancer is common in situations where women have few children and breast feed for short periods. We’ve shown that these factors alone account for much of the high rates of breast cancer in these settings.”

    Most women can rattle off a couple benefits of breastfeeding: Fewer colds and illnesses? Yep. A precious way to bond? Definitely.

    But things get a little murkier when it comes to one, potentially life-saving reason to breastfeed: a reduced risk of breast cancer. While plenty of research has established a link, it’s surprisingly hard to get straight answers. We sorted through the studies to give you the scoop.

    Medicines For Women At Higher Risk Of Breast Cancer

    The National Institute for Health and Clinical Excellence recommends that medicines be offered to some high risk women to reduce the risk of breast cancer. These are:

    • tamoxifen for 5 years if you are pre menopausal
    • anastrozole for 5 years if you are post menopausal
    • raloxifene or tamoxifen for 5 years if you are post menopausal and you cannot take anastrozole

    Your specialist doctor might also talk to you about these medicines if you have a moderate risk of breast cancer. All these drugs have side effects and are not suitable for everyone. Speak to your doctor who can tell you whether these are suitable for you.

    You do not need to take this medication if you have had surgery to reduce your risk of breast cancer.

    Australian Infant Feeding Guidelines

    The Australian Infant Feeding Guidelines recommend babies are exclusively breastfed for the first 6 months, but then extended to 12 months and beyond, for as long as both the child and mother want to continue.

    While exclusive breastfeeding is ideal, it is recognised that breastfeeding is not always easy. Any amount of breastmilk is beneficial to the infant and helps protect the mother.

    What Are The Symptoms And Signs Of Breast Cancer

    9 Proven Ways To Reduce Your Cancer Risk

    The most common symptoms and signs of breast cancer include:

    • A change in the size or shape of the breast
    • A lump, swelling or thickening in the breast area, with or without pain
    • An inverted nipple
    • Dimpling or puckering of breast skin
    • Itching, scaly soreness or rashes on the nipple
    • Red, scaly, darkened or swollen breast skin

    How Does Breastfeeding Lower The Risk Of Breast Cancer

    Now, let’s come to the main point how can breastfeeding help a woman keep breast cancer out of her future? Well, according to researchers, there are several prevalent theories about how breastfeeding helps prevent pre- and postmenopausal breast cancer:

  • Breastfeeding limits your lifetime exposure to hormones like estrogen and progesterone, which are well-known to trigger breast cancer. When youre breastfeeding, you have fewer menstrual cycles because of various hormonal changes. This leads to less hormone exposure over time and thereby prevents cancer cell growth.
  • Breastfeeding sheds your breast tissues, helping you get rid of any cells with potential DNA damage in your breasts. In order to produce breast milk, breastfeeding causes your cells to change or differentiate, which makes them more resistant to cancer-causing mutations. Consequently, neither breast cells are able to act abnormally, nor are there chances of developing breast cancer.
  • According to lactation experts, women who nurse their babies live a healthier lifestyle than those who dont. They take better care of their health by making healthier lifestyle choices, like eating nutritious foods, avoiding alcohol and smoking, exercising, etc. All these lifestyle factors play a vital role in reducing the risk of breast cancer.
  • Breastfeeding And Reduced Risk Of Breast Cancer

    Reproductive risk factors associated with breast cancer risk include age of menarche, number of pregnancies, age at first birth, lifetime duration of breastfeeding, age at menopause, and use of menopausal hormone therapy however, research has found that these factors are differentially associated with each subtype.5 Breastfeeding is of particular interest for breast cancer prevention because it is a modifiable risk factor. Breastfeeding not only reduces breast cancer risk but also confers other health benefits to the mother including reduced risk for endometrial and ovarian cancers8 and reduced risk for chronic conditions that are also risk factors for cancer, such as hypertension and diabetes.9,10 Additionally, breastfeeding provides many benefits to the infant, including fewer episodes of diarrhea, ear infections, and lower respiratory infections and a lower risk of sudden infant death, diabetes, asthma, and childhood obesity.11

    Here are three reasons researchers offer:

  • Breastfeeding lessens your contact with hormones that promote breast cancer growth. While you are breastfeeding, your menstrual cycle may be delayed because of hormonal changes. So you have less lifetime exposure to hormones like estrogen which are linked to cancer cell growth.
  • Breastfeeding matures your cells and also sheds breast tissue. Pregnancy and breastfeeding cause your cells to differentiate in order to produce milk. This process may help cells resist becoming cancerous. In addition, you shed breast tissue while nursing, so your body can get rid of damaged cells with cancer potential. Lastly, while your cells are consumed with making milk, they have less opportunity to do anything else .
  • Breastfeeding encourages you to take better care of your health. You are likely to be more mindful of the food you eat and to be concerned about smoking or alcohol abuse. Most breastfeeding women are also able to lose weight more steadily. These lifestyle habits can reduce breast cancer risk.

    Does Breastfeeding Really Reduce Your Risk Of Breast Cancer

    Does breastfeeding reduce the risk of breast cancer?

    Yes, it does, though the specifics are hard to pinpoint. There are four studies worth noting.

    A large-scale analysis of nearly 150,000 women published in The Lancet in 2002 found that for every 12 months of breastfeeding , the risk of breast cancer decreased by 4.3 percent, when compared to women who didnt breastfeed at all.

    Then a 2009 study of more than 60,000 women published in the Archives of Internal Medicine found that women with a family history of breast cancer reduced their risk of getting the disease before menopause by nearly 60 percent if they breastfed.

    A study published this year by the Journal of the National Cancer Institute found that women of African ancestry have an especially high risk of developing the aggressive and hard-to-treat forms of breast cancer called estrogen receptor-negative and triple-negativeand the risk actually goes up when a woman gives birthbut breastfeeding negates this risk.

    There seems to be growing evidence that breastfeeding is associated with a lower risk of the really aggressive kinds of breast cancer, says Alison Stuebe, M.D., an assistant professor of obstetrics and gynecology at the University of North Carolina at Chapel Hill and the lead author of the Archives of Internal Medicine study.
